The paper presents some information about the problems of noise produced by the engines. Recently, the international standards of the ICAO standard for aircraft noise reduction are constantly being tightened. The solution to this problem, in recent years, is the use of resonant sound-absorbing honeycomb panels installed in the air intake channel and in the external circuit of the engine. Today, due to the discrepancy in noise level, Russian aircrafts cannot fly on international lines with a full load. The reason for this is the lack of sound-absorbing characteristics of carbon fiber, as well as carbon fiber is quite fragile and not shock-resistant material, which also affects the operation of aircraft engines. In order to increase the acoustic efficiency and increase the strength characteristics of the aircraft engine hood, a variant of a three-layer honeycomb panel using basalt fabric and basalt-plastic fiber is being developed.
